Deep penetration arrow insert

Abstract

The deep penetration arrow insert comprising a point receiver and an insertion rod extending longitudinally therefrom is invented. The point receiver is formed with a taper varying from zero to fifteen degrees (0-15°), along its length and the taper provides for a smooth transition between point and arrow thereby minimizing aerodynamic drag. As a result, a turbulence free transition and improved penetration of a target can be provided. The insertion rod with a number of circumferential rings and these rings provide for the addition of an adhesive to secure the rod within the arrow shaft. Thus, the deep penetration arrow insert of the present invention provides for an accurate shooting arrow for target and hunting which penetrates deeper and better than conventional arrows, by providing for decreased friction along the length of the shaft.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of the U.S. Provisional Patent Application for “Deep Penetration Arrow Insert,” Ser. No. 61 / 385,824, filed on Sep. 23, 2010, the disclosure of which is fully incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates general to archery products, and more specifically to arrow components. The present invention is more particularly, though not exclusively, useful as an insert for mounting to an arrow shaft and receiving an arrow point for target and hunting.[0004]2. Description of the Related Art[0005]Many different types of arrows and arrow shafts are known for use in hunting and sport archery. The most common form of arrow consists of a shaft with an arrowhead attached to the front end and with fletching and a nock attached to the other end.[0006]The shaft is the primary structural element of the arrow, to which the other...

AI Technical Summary

Benefits of technology

[0011]The deep penetration arrow insert of the present invention includes a point receiver and an insertion rod extending longitudinally therefrom. The point receiver is formed with a taper along its length from a front diameter substantially the same as the outer diameter of a typical arrow point, and decreasing in diameter to the approximate outer diameter of the arrow shaft being used. The taper is linear, and provides for a smooth transition between the diameter of the point, and the smaller diameter of the shaft to provide improved flight characteristics and penetration of a target.

[0013]The deep penetration arrow insert of the present invention provides for an accurate shooting arrow for target and hunting which penetrates deeper than conventional arrows. As the point penetrates the target, the diameter of the hole created in the target by the penetrating point is slightly greater than the diameter of the arrow shaft. As a result, there is decreased friction along the length of the shaft and the force of the arrow is absorbed entirely by the arrow point striking the target, and not distributed partially through the friction of the shaft as it passes through the target. This focused contact on the point results in an arrow equipped with the deep penetration arrow insert of the present invention penetrating much deeper than a similar arrow having an identical shaft and point.

Problems solved by technology

However, even though the arrows are made with extreme care, the slightest imperfection, or air movement, will cause some unbalanced turbulence in air flow.

As the arrow flies through the air, it drags the adjacent air along, creating boundary layers of air with different velocities along the arrow resulting in friction.

Thus, it has been understood that mere dependency on the fletching for the accurate flight of an arrow is not enough anymore for the improved flight characteristics and penetration of arrows.

However, when the point receiver has the identical diameter as that of a shaft, unpredictable turbulence in air flow along the length of the shaft has still been inevitable.
